Across
- 3. patient positioning where patient is lying down
- 6. controls size of x-ray beam to minimize scatter radiation
- 7. device used to measure x-ray exposure
- 9. tangential radiographic view of any structure
- 11. negatively charged electrode within x-ray tube
- 13. expose thoracic radiographs at maximum ______
- 14. speed with which electrons transfer energy
- 15. stack on top of each other
- 18. accidental or unintentional image on radiographic image
- 20. outside edge or shadow where film has been imperfectly collimated
Down
- 1. proportions of radiographed object are altered unevenly
- 2. built into collimator to remove low-energy x-rays from beam
- 4. improve image quality by reducing scatter radiation
- 5. radiation intensity is greater on the cathode side
- 8. Positioning in which the primary beam enters the body at an angle
- 10. transforms remnant radiation from patient to a visible image
- 12. square law exposure reduced by square of distance from patient
- 16. portion of x-ray image that is sharp & clearly collimated
- 17. energy produced within cathode to create potential x-ray beam
- 19. positively charged electrode within x-ray tube
